Checking the Rolling Torque of the Wheel Hub
Use 9U-5017 Torque Wrench and check the rolling torque of wheel hub (1). The rolling torque should be 25 5 N m (18.44 3.7 lb ft). If the rolling torque is too great, this indicates that the bearings are restricted.

Checking the Gear (Support) with the Dial Indicator
Set a dial indicator to zero onto the surface of gear (support) (3) .
Illustration 4 g00728178
Use the dial indicator which has been set to zero in Step 3 and check the distance between the outer surface of roller bearing (2), and the plane of steering case (4) .
Assemble a shim pack (5) that is equal to the measurement that was taken in Step 4. Install the shim pack and gear (support) (3). Tighten bolts (6) .
Check the rolling torque of wheel hub (1) again with 9U-5016 Torque Wrench. The maximum rolling torque that is allowable is 45 5 N m (33.2 3.7 lb ft).Note: Shims (5) are available in the following thicknesses: 0.15 mm (0.0059 inch), 0.20 mm (0.0079 inch) and 0.50 mm (0.0197 inch). A shim with a thickness of 0.2 mm (0.0079 inch) will change the rolling torque by approximately 10 N m (7.3756 lb ft).
When the wheel bearing adjustment is correct, remove bolts (6) in order to prepare for final installation. If the bolts that are used are bright, coat the bolt with anti-seize grease before applying 9S-3263 Thread Lock Compound to the threads of the bolt. If the bolts that are used are plated, apply 9S-3263 Thread Lock Compound to the threads of the bolts only.
Install bolts (6). Tighten the bolts to a torque setting of 285 15 N m (210 11 lb ft) if the bolts are plated. Tighten the bolts to a torque setting of 315 15 N m (232 11 lb ft) if the bolts are bright.
Install shim (7) between pinion (8) and washer (9) in order to give a pinion end play of 0.4 0.1 mm (0.0157 0.0039 inch).Note: Shims (7) are available in the following thicknesses: 0.10 mm (0.0039 inch), 0.20 mm (0.0079 inch), 0.30 mm (0.0118 inch) and 0.50 mm (0.0197 inch).
